CHURN FOR GHURNING BUTTER.

Specification of Letters Patent No. 831, dated July 9, 1838.

To all whom it may concern Be it known that I, DANIEL Osoooo, J r., ofBluehill, in the county of Hancock and State of Maine, have invented anew Churning-Machine, which I have denominated Osgoods Double-SwingChurn.

This improvement consists in the machinery by which the dasher of thecommon hand churn is made to move up and down by the gravity of themachine, and the cream. It is so constructed that the power required inits operation, compared with the common churn is nearly in proportion tothe power required to draw a pendulum in its lateral motion comparedwith that of raising its weight. This saving of labor is acquired byplacing two common churns, Figure 3 (a a) on a swinging platform (6).This platform is made to swing by being suspended in the frame A, B, C,D, by a rod passing through the frame and two pieces (03 d rising fromthe sides of the platform (6) and connected underneath it by a strip ofboard framed into them (0) and supported by another bar or strip ofboard (f) at their tops. In order to produce the motion of the dashers,two other pieces of wood (9 g) of the same size of the side pieces (dcl) strongly framed together by a bar (7a,) are suspended and kept inplace by another rod,

(z' 71,) passing through them and the top of the frame, in the center ofthe bar (h,) and strongly fastened to it runs at right angles a lever(j,) to the end of which the dashers (7a,) are fastened. The ends of theside pieces (d, 03,) and the corresponding upper,

pieces (g, 9,) are cut into teeth or cogs (Z Z,) and mesh into eachother so that by swinging the platform (12,) by the handle (m,) backwardand forward the end of the lever (j,) alternately raised and depressedgiving the downward and upward motion to the dashers.

The dimensions of a machine of suitable 1 ft. 7 inches (0, 0,) diameterof the churn at the bottom 14: inches at the top, 12 inches; timberfor'frame 1. inches square (Fig, 2, E, F). The beam attached tothedashers,

its length from the center of the dashers 1 ft. 4 inches the bigness 2by 1 inches, (G,

Spread of the legs 2 ft. 6 inches (g, h)stand or platform length 2 ft. 6inches breadth 1 ft. (1,) the pendulum, from the rod'it plays on, downto the top of the platform 1 ft. 4 inches, its breadth 5% inches,thickness 5; inch; from the rod up to the center of the cogs 6 inches,the center of the beam that is attached to the dashers, is 5 inchesbelow the rod it plays on, cogs or teeth in theupper end of thependulum, six in the piece above it which matches, with it pins .i,) thehandle by which the machine is worked, and is attached to the platformby allook and staple. WVhen but one churn isnecessary,

the other may be dispensed with by substi; tuting any other weight inits stead to balance the one that is used.

WhatI claim as of my invention is I The manner in which the .da'shersare; worked by the pendulous motio-n of the churn in mannersubstantially as above de scribed.
